Convection, conduction, and overall u. a gas at 450 k is flowing inside a 2-in. steel pipe, schedule 40. the pipe is insulated with 51 mm of lagging having a mean k = 0.0623 w/m · k. the convective heat-transfer coefficient of the gas inside the pipe is 30.7 w/m2 · k and the convective coefficient on the outside of the lagging is 10.8. the air is at a temperature of 300 k. calculate the heat loss per unit length of 1 m of pipe using resistances. repeat, using the overall u0 based on the outside area a0.

answer:

not me

explanation:

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
